No it all started when I got a new fish from a friend.I didn't quarantine it.I had put him in with this guy first in a divided 120gl.And after a few day is when I put him in the other tank.Very frustrating.I have not had this much trouble in the last 15 yrs or more.All the others are fine now.I did not notice this guy was sick for quite awhile because I had put him in a 29gl one the bottom of a 3 tank stand with no light.It wasn't tell he quit eating that I put a light on him and seen he was sick.He is back to eating and look better this morning.I was just worried since I have $200 in him.
